What Sheep Producers Need to Know About New World Screwworm
June 10, 2026
New World screwworm is a serious livestock pest that can affect sheep, cattle, goats, wildlife and other warm-blooded animals. Because early detection and rapid response are critical, ASI has developed a producer-focused reference guide designed to help sheep operations understand the risks and prepare before the pest reaches their area.
The guide includes information on:
- What producers should do now to protect their operations.
- How New World screwworm affects sheep and other livestock.
- Warning signs and symptoms to watch for.
- Practical steps to minimize risk.
- Veterinary treatment considerations.
- Important contacts and additional resources.
ASI says the guide is intended to provide producers with the information they need to recognize potential cases and work with veterinarians and animal health officials if concerns arise.
Sheep producers are encouraged to review the guide and incorporate recommended biosecurity and monitoring practices into their operation's management plan. As New World screwworm surveillance and response efforts continue, staying informed remains one of the best tools available to livestock producers.
